HYDRANT.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed February 17, 1909. Serial No. 478,515.

To all whom it may concern.'

Be it known that I, VALTER K. PALMER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydrants, of which the following is a specification.

This invention relates to hydrants and my object is to produce a hydrant composed of parts which can be readily assembled to constitute either a right-hand or left-hand hydrant and of such construction that when the water is turned on it shall have a free and entirely unobstructed passage or path through the valve as well as through the body of the hydrant.

A further object is to produce a hydrant of such construction that the water cannot be turned 'on by the breakage of or any other injury tothe hydrant above the valve-casing.

A further object is to produce a hydrant having a conical valve-seat and a conical valve of such construction that the pressure of the water shall be utilized to force the valve against its seat and thus guard against leakage and compensate for wear and also tend to hold the valve either open or closed.

Another object is to produce a frost-casing which can be readily applied to the standpipe or barrel of the hydrant to protect the saine to a suitable depth below the surface of the ground, and a still further object is to produce a hydrant of simple, strong, durable and inexpensive construction.

lith these objects in view the invention consists in certain novel and peculiar features of construction and organizationas hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which U Figure l, is a central vertical section of a hydrant embodying my invention. Fig. 2, is a horizontal section taken on the line tI-H of Fig. 1. Fig. 3, is a detail central vertical section of the frost-casing. Fig. t, is a horizontal section of the frost-casing. Fig. 5, is a top plan view of the hydrant. Fig. 6, is a top plan view of the valve detached from the hydrant. Fig. 7, is a front elevation of the valve. Fig. 8, is a horizontal section on the line VIII- VIII of Fig. 1. Fig. 9, is a horizontal section on the line IX-IX of Fig. 1. Fig. 10, is an inverted plan View of the operating mechanism, a washer forming an element of the same being broken away to avoid hiding another element. Fig. 11, is a fragmentary vertical section of the stand-pipe enlargement to show certain grooves therein.

In the said drawings, 1 indicates a standpipe provided with one or more nozzles 2 at its upper end and terminating at its lower end'in a curved divided-passage portion 8 and adapted to be coupled in any suitable manner at such end to a water-supply pipe, not shown, embedded in the ground, it being also noted in this connection that the stand-pipe for a suitable distance above its curved lower end, is also buried in the ground. At a suitable point in its curved portion the pipe is cast with a hollow conical enlargement l connecting and communicating with the divided-passage portion, and is flanged outward at its lower' end as at 5, and above said flange the conical enlargement is formed with a chamber 6 communieating with the interior of the enlargement and located by preference, diametrically opposite the lower end of the curved portion 3, and communicating with the adjacent ends of a pair of grooves 7a in the inner face of the. enlargement and extending concentrieally of the axis of the same, the top of the portion 7 which forms the chamber 6, being equipped with an upwardly-projecting boss 8 having a vertical passage 9 reduced in diameter near its lower end to form an upwardly-disposed seat 10. Avertically above boss S the stand-pipe is equipped at its upper end with a boss 11 having a passage 12 vertically aliiied with passage 9, and fitting at its lower and upper ends respectively, in passages 9 and 19, is a tube 13 seated at its lower end on seat 10.

14; is a rod extending longitudinally through tube 13 and journaled at its lower end in portion 7, its upper end being equipped with a collar 15 having a cyliiidrical depending stem 16 journaled in boss 11 and adapted to guard against upward movement of tube 13, a set-screw 17 being utilized to secure collar 15 rigidly upon rod 14. The rod terminates above the collar in a squared head 18 for engagement by asuitable handle, not shown, for turning the rod, and the lower end of the latter is reduced to forni a spindle 19 upon which is rigidly secured a gear-pinion 20, the preferred means for securing said gear-pinion in place, being a key 21 which engages registering grooves in the spindle and gearpinion, and a washer 22 fitting on the spindle and held in such position by a cotter 225 or its equivalent. It will be noticed, in this connection, that the chamber 6 is of su'tlicient depth to permit the pinion, key, washer and cotter to be secured in or removed from position after the rod has been secured in place, access to the parts referred to being had from the interior of the conical enlargement f1.

24 is a hollow conical valve to lit snugly in the conical enlargement 4;, and formed with a tubular passage 25 ot' the same diameter and radius as the divided passage of the curved end of the stand-pipe, so that when the valve is open its passage 25 shall form in effect, a part of the passage of the stand-pipe in order that the volume of water passing through the valve shall be unobstructed and ot' same diameter as that which passes through the curved portion ot' the stand-pipe and thus not interfere with or retard the flow ot the water. The valve is provided with an upwardly-disposed external shoulder 26 in the horizontal plane of chamber 6 and grooves 7a, and secured rigidly on said shoulder in any suitable manner and projecting into said grooves '7a is a segmental rack-bar 27 having a series of teeth extending from near one extremity of the bar to a point beyond its center and meshing with the pinion 20, the arrangement being such that when the pinion is in engagement with the rack-bar near one extremity, the valve will be closed and when in engagement with the opposite end of said series ot teeth, the valve will be open.

To seal the lower end ol the conical enlargement- L1- and conical valve 2a, a baseplate 28 is bolted as at 29, to flange 5, and in order that water, under pressure, may pass into the valve externally of the tubular poi'- ti'on forming passage 25 for the purpose of pressing the valve upwardly against its seat, the valve is provided with a pair of ports 30 at opposite sides or" its tubular portion, which ports when the valve is open, communicate with water-ways 31 in the inner face of the conical enlargement L at opposite sides ot stand-pipe portion 3, said waterways communicating at their inner ends with the lowei' extremity of portion 3 of the stand-pipe, the arrangement being such that when the valve is closed by turning it to the position shown in dotted lines Fig. 9, one of its ports 3() is moved into communication with the water-way 31 at the opposite side of the lower portion of the stand-pipe so that water from the latter may enter the chamber and keep said valve pressed upwardly against its seat.

For the purpose of draining the water from the stand-pipe the valve is provided externally with a water-way 32 connected to the lower end of the valve-passage 25 and normally closed by the conical enlargement el, and adapted, each time the valve is closed,- to register with one of a pair of drain-holes 33 in the enlargement 1.

Assuming that it is desired to assemble the parts so as to form a left-hand instead of a right-hand hydrant, the position of the rack-bar 27 with reference to the valve, is reversed, that is to say, the rack-bar is inverted so as to dispose its teeth on the opposite side of the center of the valve from that shown in Fig. 6. lit-h this arrangement the handle is turned to the let't to open the valve as will be readily understood, it being of course apparent that if the hydrant was adapted for operation only as a right-hand or a lett-hand hydrant, only one of the drainholes 33 would be needed and only one orn the ports 30.

BJC is a frost-casing embracing the standpipe and the tube 13 from a point a suitable distance above to a point a suitable distance below the level of the ground, and said casing preferably consists of two semi-conical sections 35 and 36 provided with inwardlyprojecting semi-circular ring-flanges 37 and 38 at their upper and lower ends to tit snugly against the pipe and space the body ot the casing away from the pipe to provide an air chamber tor insulating purposes, the upper and lower flanges of section having openings 39 to accommodate the tube 13. The vertical margins of one section of the frostcasing are formed for nearly their full length, with inwardly-projecting hooks 40 and the corresponding margins of the other section are formed with inwardly-projecting ribs L,l1 to engage said hooks with a dove-tail relation so that the two sections are adapted to be fitted together with their ends out of alinement and then slid in opposite directions until said ends are alined. TWhen' thus arranged they cannot be disconnected without reversing such manipulation. It will thus be seen that said sections can be reliably secured together easily and expeditiously without the use of bolts or rivets.

From the above description it will be apparent that I have produced a hydrant embodying the features of advantage enumerated as desirable and which is obviously susceptible of modification in minor particulars without departing from the spirit and scope of the appended claims.
